DECT 6.0 digital technology
The AT&T DECT 6.0 products offer unsurpassed range performance and sound clarity. This is 
achieved through a unique antenna design and advances in noise-filtering technology. An 
independent laboratory has confirmed that AT&T DECT 6.0 products perform up to 45% better 
in range competitions. Now calls can be taken in the basement, backyard and garage with 
exceptional sound quality.  
Telephone operating range
This cordless telephone operates within the maximum power allowed by the Federal 
Communications Commission (FCC). Even so, this handset and telephone base can communicate 
over only a certain distance — which can vary with the locations of the telephone base and 
handset, the weather, and the construction of your building. 
Redefining long range coverage and clarity
This telephone base comes with two antennas that gives much better clarity and covers a longer 
range than before. For even greater range, add optional repeaters (AT&T model SB67128).
